The housing includes a chamber, a wind outlet, and a wind inletlocated slantingly. The water guide member includes a hollowed portion,a water inlet, and a water outlet. The drive device includes atransmission shaft and a pumping member. The transmission shaft has oneend connected with a propeller assembly mounted in the chamber of thehousing. The pumping member is mounted in the hollowed portion of thewater guide member and to the other end of the transmission shaft. Aflange is mounted between the chamber and the water guide member, havinga plurality of fix holes. A bearing is mounted to where the transmissionshaft is pivoted to the housing. A wind-incoming member is mounted tothe wind inlet slantingly, having a tapered threaded hole connected witha pipe coupling for connection with a gas pipeline.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIGS. 1, 2 & 4, a coolant pump A for processing machineryin accordance with a preferred embodiment of the present invention iscomposed of a housing 1, a water guide member 2, and a drive device 3.

The housing 1 is bell-shaped and includes a chamber 11, a wind inlet 12,a wind outlet 13, a wind-incoming member 14, and a pipe coupling 15. Thewind-incoming member 14 is located slantingly at the wind inlet 12,having a tapered hole 141 and an internal thread 142 connected with thepipe coupling 15 for connection with an air pressure pipeline 16.

The water guide member 2 is shaped like a strut, including a hollowedportion 21, a water inlet 22, a water outlet 23, and a flange 24. Thewater inlet 22 is located above a center of a top side of the hollowedportion 21. The flange 24 has a plurality of fix holes 241. A chassis 27is mounted to a predetermine position above the flange 24, having athrough hole 271 running through a center thereof. The chassis 27 andthe housing 1 are connected with each other to define a closed chamber.The water outlet 23 is located at a right side between the flange 24 andthe chassis 27, having an internal thread 231 connected with the pipecoupling 25 for connection with a water pipe 26. In this way, the waterinlet 22, the hollowed portion 21, and the water outlet 23 jointlybecome a passage for a coolant 42.

The drive device 3 includes a transmission shaft 31, a pumping member32, and a blade assembly 33. The pumping member 32 is mounted in thehollowed portion 21 of the water guide member 2 and to one end of thetransmission shaft 31. The other end of the transmission shaft 31 isconnected with the blade assembly 33. The blade assembly 33 is mountedin the chamber 11 of the housing 1. As shown in FIG. 3, the transmissionshaft 31 passes through the through hole 271 and the water inlet 22, anda bearing 32 is mounted between the housing 1 and the transmission shaft31 and to the through hole 271.

Referring to FIGS. 4 and 5, the coolant pump A is partially installed ina coolant container 41, and the flange 24 is fixed to a predeterminedposition above the coolant container 41 in such a way that screws areinserted into the fix holes 241. In this way, a lower part of thecoolant pump A is dipped in the coolant 42, located below the flange 24.An upper par of the coolant pump A is connected with the air pressurepipeline 16 at the pipe coupling 15 thereof, located above the flange24. The pipe coupling 25 is connected with the water pipe 26. An airpressure is introduced through the water inlet 12 and flows to the bladeassembly 33 sidewards and then out of the wind outlet 13, such that anairstream is generated in the chamber 11 to drive rotation of the bladeassembly 33, the transmission shaft 31, and the pumping member 32 tofurther pump the coolant 42 through the water inlet 22 into the waterguide member 2 and then through the water outlet 23 and the water pipe26 to the processing machinery for cooling a cutter of the processingmachinery. Because the wind inlet 13 is provided with a tapered hole141, the introduced air pressure can though gradually and slowly expandto lower the noise generated when the air pressure is ejected, but thetapered hole 141 cannot fully eliminate the noise. If it is necessary tofurther lower the noise, a silencer (not shown) can be mounted to thewind outlet 13.

Referring to FIG. 6, the coolant pump A is connected with the airpressure pipeline 16, the water pipe 26, and the processing machinery,wherein the water pipe 26 is connected to where is adjacent to agrinding wheel of the processing machinery. The coolant pump A can pumpthe coolant 42 from the coolant container 41 to where is adjacent to thegrinding wheel and then the coolant 42 flows outside. In addition, theintroduced air pressure has been filtered by a pneumatic device to belubricative clean air and then the clean air is adjusted by a flowregulator for a proper pressure. Besides, the air pressure can beapplied to any processing machinery, which will produce chippings, aslong as treated by a cooling device 4 of the coolant pump A.

In conclusion, the present invention can attain the following effects.

1. The present invention facilitates the assembly to the processingmachinery and the maintenance, such that the product cost can bereduced.

2. The present invention is powered by the air pressure, such that noshort circuit or electric shock will happen. Besides, the presentinvention is structurally simple and durable to have a long working life
